Answer:

22 square millimeters

Explanation:

Given,

Parallel sides of the trapezium = 3mm, 8mm

Height of the trapezium = 4mm

Therefore,

Area of the trapezium


= (1)/(2) * (sum \: of \: parallel \: sides) * height


= (1)/(2) * (8 + 3)mm \: * 4mm


= (1)/(2) * 11mm * 4mm

= 11mm × 2mm


= 22 {mm}^(2)

Hence,

Area of the trapezium is 22 square millimeters (Ans)
